The leaves are oblong or oval-lanceolate, with dark ellipsoid-shaped spots on the surface (hence the species name). The leaves are amplexicaul and can be either radical (basal) or cauline. The underground part of the stem has two webbed tubers, each deeply divided into several lobes or tubercles (characteristic of the genus Dactylorhiza ).
Black rot on orchids is caused by Pythium and Phytophthora species. [1] Black rot targets a variety of orchids but Cattleya orchids are especially susceptible. [1] Pythium ultimum and Phytophthora cactorum are known to cause black rot in orchids. [1] Pythium ultimum is a pathogen that causes damping-off and root rot on plants. [2]
The English name 'common spotted' refers to the species' abundance and the spots on its leaves. The French and German common names also honour Leonhart Fuchs. This plant belongs to a problematic group of orchids. D. maculata subsp. fuchsii is very variable in flower colour and flower morphology, plant height and the scent of flowers.
Pseudochromis fridmani is a species of fish in the family Pseudochromidae, the dottybacks. Its common name is orchid dottyback. It is endemic to the Red Sea.

Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the genus Ophrys, in the family of Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, a highly selective and highly evolved plant–pollinator relationship.
Tipularia discolor is an orchid with a reddish brown stem and dull yellow to purplish brown weakly monosymmetric flowers. [10] The leaves of the orchid are easily distinguished as they are ovate with a bright green adaxial surface (top) and a purple abaxial surface (bottom). In autumn, a single leaf emerges, which lasts throughout the winter. [11]
Apolemichthys trimaculatus is a bright yellow species of angelfish which has blue lips, a wide black margin to the anal fin, a black spot on the forehead and a faint spot just to the rear of the operculum. The juveniles do not have the spots and show a thin black band running vertically through the eye and vertical golden barring on the flanks. [4]
The elder-flowered orchid prefers fresh or dry meadows (subalpine and alpine grasslands), light woods and clearings or scrubland. They grow on siliceous and calcareous substrate, at an altitude of 300–2,000 metres (980–6,560 ft) above sea level, although locally, for instance in Uppland , Sweden , they can be found at sea level as well.
